Abstract :Auditory neuropathy spectrum disorder contains clues from dysfunction in the region extending from the auditory structures in the inner ear to the auditory brainstem. It can be observed especially with the presence of oto-acoustic emission, as well as the absence of auditory brainstem response or severe disturbances in wave morphologies. Cochlear implant is one of the treatment methods for this disorder and is preferred by clinicians in order to contribute to speech perception and language development. Here, some cochlear implant candidacy criteria come into play and the implantation option is applied if the necessary conditions are met for the auditory neuropathy spectrum disorder patient population. In this study, the effects of cochlear implant on auditory neuropathy spectrum disorder were compiled by including the researches of the last 10 years. As a result of the studies, it was determined that the cochlear implant improved postoperative speech perception and contributed positively to language development in the auditory neuropathy spectrum disorder population without the presence of any comorbidity. However, more studies with high evidence are needed for the effect of cochlear implant on auditory neuropathy spectrum disorder in the presence of comorbidity.
